New focus for application staining negative Virus. thanks to our feedback from UranyLess users around the world. some users for specific applications reported that their results for viruses with negative staining were average to poor. Our Laboratory Research and Development, has just made technical adjustments of the Uranyless which gives excellent results for all applications in positive or negative staining (We are always interested in your feedback, contact us at info @ deltamicroscopies. com). We have developed for this application with a German Laboratory (especially thanking Dr André DIESSNER) Icon Genetics GmbH - D - 06120 Halle / Saale we present you, their negative staining results with Uranyless Image Description.
